Figure 4From: The Dictyostelium genome encodes numerous RasGEFs with multiple biological rolesMorphology of gef mutant cells. Vegetative AX3 and gef null cells were grown in axenic medium in tissue culture dishes for 24 h and visualized by phase-contrast microscopy. The white bar represents 20 μm. Mutants in gefK and gefL were observed on different occasions but were similarly comparable to the parental strain.Back to article page
